Describe the feature

An issue I ran into was not being able to make corner stairs with either of the framed sliced stair blocks. I would think it would be great to be able to have this as a feature.

This is possible in the 1.21 release of FramedBlocks due to all two-material stairs blocks now having vanilla stairs connection behavior. Back porting this to 1.20.1 is unfortunately not possible for technical reasons.
